    • A motor-and-pump assembly includes armature shaft of the electric motor which is retained in the pump housing by way of a main bearing and an auxiliary bearing.The objective is to align the motor housing centrically to the axis of the armature and, in addition, to achieve a reliable attachment of the motor housing to the pump housing.Therefore, the housing of the electric motor has a bowl-shaped design, and the rim of the motor housing is inserted into a concentrically circumferential groove in a flange surface on the pump housing. The diameter of the inner wall of the groove corresponds to the inside diameter of the motor housing. Thus, the inside wall of the motor housing abuts on the inner rim of the groove. The motor housing is thereby aligned centrically.The motor housing can simply be fastened to the pump housing by a clamping ring which is also inserted into the groove.

    • The present invention relates to a piston pump, in particular to the arrangement of the bearing ring for supporting the pump piston on an eccentric. The pump bearing includes a bearing ring and a plurality of bearing needles. The peripheral surface of the eccentric is radially inwardly offset in relation to the peripheral surface of the shaft. The two stepped transitions provide stop surfaces for the bearing needles. The bearing ring is supported on an inner ring for a main bearing, on the one hand, and, on the other hand, directly or indirectly on the stepped transition between a second area and a third area in a blind-end bore. Further, an auxiliary bearing is provided with a bearing ring which is made of a material inhering a high degree of wear. Testing the electric motor, used to drive the piston pump, before the piston pump is assembled is thereby permitted.
